Superior Mold-Filling Efficiency

POLYLAC PA-746H’s high melt flow index (40 ml/10 min) ensures rapid, uniform filling of intricate molds—ideal for thin-wall designs like automotive trim or electronics housings, reducing cycle times and material waste.

Reliable Impact Resistance

With Izod impact strength of 27 KJ/m² (23°C) and 12 KJ/m² (-30°C), this ABS resin withstands drops, vibrations, and cold environments, perfect for outdoor equipment or automotive components exposed to harsh conditions.

Thermal Stability Under Pressure

A Vicat softening temperature of 102°C (1KG load) ensures dimensional stability during high-heat processes like plating or assembly, minimizing warping in appliances or industrial parts.
